Two shape-selective HZSM-5 catalysts with similar pore size were prepared by silicalite-1 coating or boron modification, respectively. These catalysts samples were characterized by XRD, SEM, NH 3 -TPD, Py-IR and N 2 adsorption–desorption isotherms and tested in the alkylation reaction of toluene with methanol. The results indicated that the boron modification weakened the acidity but increased the total amount of acidity sites, while the silicalite-1 coating led to the decrease of the strong…

The effect of nano-scale P2O5-ZSM-5 aggregates (NZA), dispersed nano-scale P2O5-ZSM-5 (DNZ), and micron-scale P2O5-ZSM-5 (MZ) on para-selectivity was investigated in detail. XRD, SEM, N2 physical


Influence of the post-treatment of HZSM-5 zeolite on catalytic performance for alkylation of benzene with methanol
Abstract The porous material HZSM-5 zeolite with micro-mesopore hierarchical porosity was prepared by post-treatment (combined alkali treatment and acid leaching) of parent zeolite and its catalytic
p-Xylene selectivity enhancement in methanol toluene alkylation by separation of catalysis function and shape-selective function
Abstract Catalyst reactivity and selectivity always compromise with each other in most reactions. HZSM-5 catalyst for the methanol toluene alkylation reaction suffers from active site loss when
